Wax-pot for sewing-machines.



UNITED STATES PATENT OFFICE.

GEORGE L. CORCORAN AND GEORGE A. DOBYNE, OF ST. LOUIS, MISSOURI, ASSIGNORS TO CHAMPION SHOE MACHINERY COMPANY, OF ST. LOUlS, MISSOURI, A CORPORATION OF MISSOURI.

Specification of Letters Patent.

Patented Jan. 9, 1906.

Application filed August 4, 1905. Serial No. 272,730.

To all whom it may concern:

Be it known that we, GEORGE L. CoEooEAN and GEORGE A. DOBYNE, citizens of the United States, residing at St. Louis, Missouri, have ointly invented a certain new and useful Improvement in Wax-Pots, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a side elevational view of the frame of the wax-thread sewing-machine, showing our improved wax-pot and bobbinwinding mechanism thereon. Fig. 2 is an end elevational view of the waX-pot. Fig. 3 is a top plan view of the wax-pot, and Fig. 4 is a sectional view on the line 4 4 of Fig. 3.

This invention'relates to wax-thread sewing-machines, particularly sewing -machines used for sewing leather.

The object of the invention is to rovide a wax-pot of such construction that t e thread fed from a source of supply to the needle need not be disturbed when it is necessary to wind a bobbin. As is fully appreciated by those skilled in the art it is desirable to have the thread waxed before it passes onto the bobbin, and this waxing is usually performed in the wax-pot, and the thread is usually fed through an opening in the WaX-pot, through which the thread passes to the needle. In order to wind the bobbin, it has been necessary heretofore to break the needle-thread and wind said thread onto the bobbin, necessitating a rethreading of the machine each time the bobbin is Wound. By utilizing a wax-pot constructed in accordance with our invention the needle-thread need not be disturbed during the winding of the bobbin, as a separate supply of thread is used for the bobbin.

In order to clearly disclose our invention,

we have shown it as being applied to a machine similar to the one illustrated and described in our Patent No. 760,732, dated May 24,1905.

On the frame 1 is awax-pot 2, open at the top, so that thread may be fed thereinto from a suitable source of supply. The thread for the needle will pass through a nipple 3 in the side of the waX- ot, the o enin in the E P c:

nipple 3 being of suc diameter as to permit the thread to pass therethrough. The thread is then fed through the alternately-opening jaws 4 and 5 and over the measuring element 6 of the thread-measuring device. After the thread passes over the idler-pulleys 7 and 8 it passes over the pulley 9 on the end of the lever 10 of the take-up mechanism. In the lower portion of the wax-pot 2- is a second nipple 11, which also is provided with an opening through which the thread 12 may pass after having passed through the wax in the waX-pot 2, said thread being adapted to be led directly to the bobbin-winding mechanism 13, carried below the wax-pot and suitably secured to the machine-frame.

An independent source of supply of thread 12 is used for the bobbin-winding mechanism, the thread passing through the nipple 11. Thus when it is desired to wind the thread on the bobbin it is unnecessary to break the needle-thread; but the hanging end of the bobbin-thread may be drawn down, started on the bobbin, the bobbin placed in position on the winding mechanism, and byoperating the hand-wheel wind the bobbin with the Waxed thread in readiness to be placed in the shuttle. 7

It will be apparent that a wax-pot constructed in accordance With our invention will be a material improvement over those having but a single opening, because the time saved, which would otherwise be utilized in unthreading and rethreading the machine, will be a material factor in reducing the expense of operating the machine.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is

In a machine of the class described, mechanism for measuring and feeding a strand of thread, a wax-pot carried by the frame of the machine and having a thread-opening in its side Wall alining With said thread measuring our signatures, in the presence of two Witand feed mechanism, mechanism for Winding nesses, this 3d day of July, 1905.

thread onto a bobbin, and a thread-opening GEORGE L COROORAN in the bottom of the Wax-pot for receiving a GEORGE DoBirNE 5 second strand of thread that passes through the Wax-pot and is Wound onto the bobbin; Witnesses: substantially as described. B. F. FUNK,

In testimony whereof we hereunto aflix GEORGE BAKEWELL.
